This is a simple question on expressing numbers in decimal form. Firstly, we need to understand whole numbers and decimals. A whole number is a number without fractions or decimals. In contrast, a decimal is a way to express numbers that are not whole, using a decimal point (.) to separate the whole part from the fractional part. The numbers to the left of the decimal point represent the whole, and those to the right represent the fractional part.
